Irène Joliot-Curie (1897 – 1956)

The elder daughter of Pierre and Marie Curie, Irène followed her parents’ footsteps into the lab. The thesis for her 1925 doctor of science was on the alpha rays of polonium, one of the two elements her mother discovered. The next year, she married Frédéric Joliot, one of her mother’s assistants at the Radium Institute in Paris. Irène and Frédéric continued their collaboration inside the laboratory, pursuing research on the structure of the atom. In 1934, they discovered artificial radioactivity by bombarding aluminum, boron and magnesium with alpha particles to produce isotopes of nitrogen, phosphorus, silicon and aluminum. They received the Nobel Prize in chemistry the next year, making Marie and Irène the first parent-child couple to have independently won Nobels. All those years working with radioactivity took a toll, however, and Irène died of leukemia in 1956. - Source: Smithsonian magazine
